The utility of your average vibrator is pretty clear, right? Pleasure. Combining that purpose with anything else would normally seem unnecessary. The Duet makes its case nicely by being both a waterproof USB drive and cute little love toy.

While it's exactly the diametric opposite of a Fleshlight, the elegant Duet come close. It's made of body-safe silicone and metal, is fairly quiet, and is totally waterproof. Because everything should be waterproof. It charges via USB so you don't have to worry about batteries, and it can hold up to 16GB of data. As it is, you can forget about it being a vibe and use it as a thumb drive. One you'd probably want to keep private, but still.
